TYPEWR-ITING MACHIVNE.

Application led December To all @07mm it may concern.'

Be it known that l, EDWIN E. Banner, citizen of the United States, andresident of lil ew Rochelle, in the county of l."estchester and State ofN ew York, have invented certain new and useful mprovements inrlypewriting ll/lachines, of which the following is a speciication.

My invention relates to line spacing mechanism for typewriting machinesand its general object is to provide new and improved mechanism of thecharacter specified. specilic object of the invention is to provide foroperating pawl and ratchet line spacing f devices located at one end ofthe platen by a line spacing handle located at or near the opposite endof the platen.

To the above and other ends which will hereinafter appear.l my inventionconsists in the features of construction, combinations of devices andarrangements of parts hereinafter described and particularly pointed outin the claims.

rlhe preferred form of the invention was designed primarily for the llo.10y Remington typewriting machine, and in carrying out the invention lhave dispensed with the line spacing handle usually provided and mountednear the right hand end of the plat en and have instead provided a linespacing handle or finger piece mounted on the4 carriage near itsleft-hand end and connected with the usual line spacing pawl at theright which has been retained. The present form of my invention will bedescribed in detail in connection with the accompanying` drawingwherein- `Figure 1 is a fragmentary top plan view of the carriage of aNo. 10 Remington typewriting machine embodying my invention.

broken away or sectioned for the sake .of clearness. l y

Referring iirstto Figs. 1 and 2, the carriage of the N 0.10 Remington`machine comprises a rectangular truck composed of a front bar 1 andparallel rear bar (not shown) which are connected by end bars 3 and 4.Shiftably mounted on the truck is a platen frame vcomprising end bars 5and a cross rod 6, said frame being` connected with the truckvby links7. Rotatably mounted on the platen frame is a platen 8 having axleportions 9 ywhich pass through the end bars 5. @peratively connectedwith the platen at its right-hand side is a line spacing ratchet wheel10 with which co-operatesa line spacing pawl 11, said pawl being pivotedat 12 to a pawl carrying arm 13 which is rotatively mounted on theright-hand axle section 9. A roller detent 14 mounted on a spring arm 15co-operates with the teeth of the ratchet wheel 10. The parts abovedescribed.7 are common to the Remington machine.

In carrying out my present invention I have dispensed with the usualmeans for actuating the pawl 11 and provided instead a train ofmechanism which is operated from the left-hand end or side of thecarriage, this novel train being supported by a pair of brackets whichare detachably lmounted on the carriage truck, one at the right and oneat the left side thereof. Said brackets are shown detached in Figs. 5and 6 and are respectively designated by the numerals 16 and 17. rfheyare preferably made of sheet metal, and lthe right-hand bracket 16 com`prises a flat body portion 18, an upright end portion 19 and at vitsreary an upwardly eX- tending tab or ear 2O which is curled or bent toprovide a bearing for a stop screw 21 which is provided with a check nut22. The bracket 16 is also provided with an upstanding bearing post 23having a flange 24, said post being staked or rivetedy to the Abodyportion 18. The post 23 is located at or near the middle of the bracketconsidered from fro-nt to rear, and at` theforward end of the bracketthere is staked or'otherwise `riiXed to the body portion 18 an uprightflanged post or linger piece whose surface may be knurled or roughenedas shown in the drawing. The brackety 16 with the parts mounted on vitas described is secured to the top of the truck bar 3 near its forwardend by headed screws 26 which pass through openings indicated at 27 inthe body portion 18 and are threaded into the end bar 3. ivotallysupported on the post 23, as shown in Figsl and 2, is a bell crank lever28, said lever having a downwardly extending hub 29 which fits over andbears on the post 23, the lower end of the hub 29 resting on the flange24. A headed screw 30 threaded into the post 23 at the top preventsaccidental upward displacement of the bell crank lever 28, the head ofsaid screw overlying in part the tno-p face of said lever. @ne arm ofthe ball crank lever 28 extends forward from its bearing and the otherarm extends inward or leftward, the leftwardly extending arm beingconnected by a fore-and-aft link or thrust rod 31 with the pawl 11. Thekforward end of the link 31 is provided with an upwardly extendingangular portion 32 which is hooked through a round hole in the bellcrank arm, while the rear end of the link terminates in a laterallyprojecting angular portion 33 which is hooked through a hole in the pawl11 below the pivot 12. The con struction is such that while the link 31may be readily detached when either of the connected parts 11 or 28 isremoved, yet said link is so constructed and connected that accidentaldetachment cannot take place when the. parts are secured in position.The forwardly extending arm of the bell crank 23 has connected to it theright-hand end of a long link or tension rod 34, said link 34 at itsright-hand end terminating in a downwardly extending hook portion 35which engages in a hole in the bell crank 28. The link or tension rod 34extends longitudinally of the platen and of the carriage, said linkbeing preferably arranged or disposed behind the usual scale bar 36 andabove the rear portion of the stop rack bar member 37 that is fixed tothe top of the front bar 1 of the carriage. The scale bar 36 is securedto the topof the stop rack bar and, being narrower, leaves at the rear arecess 36a in which the link 34 is conveniently received. rEhe left-handend of the link 34 terminates as most clearly shown in Fig. 4 in adownwardly bent extension or end portion 34aM on which is looselymounted a nut 38 provided with a hexagonal head 39. rThe lower end ofthe extension 34a is spread or upset to prevent detachment of the nut38, 39. The exterior of the body of the nut is threaded to adapt it toengage in a tapped opening formed in the rear arm 49 of a lever niemberof the first order which further com* prises a forwardly extending arm41V terminating ina downward extension or finger piece 42. Said memberor lever 40-42 is provided with a hub portion 43 which is drilled out tofit over and bear on a post 44, said bearing post being provided with aflange 44a on which the hub of the lever 42 is adapted to rest. A screw45 is threaded intov the top of the post and is provided with a headwhich in part overlies the hub 43 and prevents upward displacement ofthe operating lever 40-42 rThe post 44, 44L is staked into or otherwisefixed to the body portion 46 of the left-hand bracket 17, said bracketfurther comprising an angularly disposed upright end portion 47. At itsrear the bracket 17 is downwardly bent or offset, the downwardly bentrear portion being formed with a slot indicated at 48 which is adaptedto receive a headed screw 49 that is threaded into the truck bar 4. 50(Fig. passes through the bracket and is threaded into the carriagetruck, the two screws 49 and 50 detachably securing the bracket 17 tothe left-hand end of the carriage. 1n order to provide room for thebracket 17, the usual left-hand release lever of the machine, whichlever has a key or finger piece that overlies the front lefthand cornerof the carriage truck, is replaced by a release lever 51 which ispivo-ted at 52 to the side of the truck or carriage frame and terminatesat its front end in a finger piece or key 53. The release key or fingerpiece 53 unlike the prior construction, is bent leftward from the bodyportion 51 instead of rightward and thus leaves the corner of thecarriage truck clear for the attachment of the bracket 17. The inner endportion 47 of the bracket 17 abuts against the left-hand ends of thebars 36 and 37, said portion 47 being cut out or shaped to conform tothe shape of the bars whose ends are housed or covered by the said endportion 47, a notch, indicated at 54 in the part 47 affording apassageway for the connecting rod or wire 34. Similarly the end portion19 of the bracket 16 covers the right-hand ends of the bars 36 and 37,said, portion 19 being cut away as indicated at 55 to afford passagewayfor the connecting rod 34. The provision of the end portions 19 and 47on the two brackest 16 and 17 enables me to dispense with the usualangular end pieces that cover the ends of the sca-le and rack bars. rfhedisposition of the rod or wire 34 in the recess 36 formed by the bars 36and 37 renders the rod inconspicuous and serves also partly to protectit. 1n order further to guard and protect the long rod or wire 34 thereare preferably provided several, two in the present instance, fingers orcurved sheet metal guards 56. These are detachably secured by screws A57to the top of the rack bar member 37 and curve over from the front andcover 'the top of the rod 34. The ngers 56 are disposed at oppositesides of the usual pointer 58 which curves forward over the top of therod 34 oppositely from the fingers 56.

The handle or finger piece 42 in which the forward arm 41 ofthe'operating lever ter- Another headed screw' minates extends downwardat the yleft of the carriage, overhanging the rear portion oi thekeyboard oi the machine in a position convenient to the left-hand of theoperator. lt will be understood that the handle serves the do-ublepurpose of restoring the carriage from lett to right and also otconcurrently line spacing the platen by actuating the pawl and ratchetmechanism at the opposite or right-hand end of the platen. Normally theparts may be arrested in the Fig. l position by reason of the contact ofthe bell crank 28 with the rear edge of the relatively stationary part19 which acts as a stop Jfor the operating train; but any other suitablestops may be provided. During line spacing operationsv the handle 42 ispushed toward the right, turning the operating lever on its fulcrum andswinging the rear lever arm 40 toward the left, thus communicating aleftward pull to the rod 34 which will thereby be moved generallylongitudinally le'litward. This leftward movement of the rod will inturn transmit a rotary movement to the bell crank 28 swingthe leftwardlyextending arm of saidy bell crank rearward and thrusting the link or rod3l rearward, thereby actuating the pawl 11 and causing it to co-operatewith the ratchet wheel l() in the usual way to turn the ratchet wheeland the platen through one or more units of line space distance. lt willbe understood of course that the extent of line space turning movementcommunicated to the platen will depend on the adjustment of the usualline space regulator (not herein shown).

In order to limit movements of the actuating train in line spacingdirection and also to overcome a tendency on the part of the platen andplaten frame to shift or move upward as the result of an excess of powerapplied to the line spacing handle, the stop screw 21 is provided. Theforward end of this screw lies in the path of movement of thehorizontally arranged bell crank 28 and said screw is so adjusted andlocked or set by the nut 22, that it will arrest the hell crank when thefull line spac-y ing turning movement thereof has been completed,thereby preventing excess move- Y ments of the bell crank which might becommunicated through the link 3l to the pawl ll.

For the purpose of restoring the train of mechanism, beginning with thehandle 42 and terminating with the pawl l1, a single restoring meansonly is necessary; this means being in torni of a wire spring 59 whichis coiled around the hub 29 and the {lauge 24, said spring beingconfined between the top of the bracket part 18 and the under side otthe bell crank 28. The lower end ot the spring 59 is extended straighttowards the rear and abuts against theinner side of the ear 2O whichwill hold' it againstl The upper end of unwinding movement. the spring59 is extended outward away from the coil and is held against unwindingmovement by a pin 60, which extends downward from the under side of bellcrank 28, the straight end portion of the spring pressing againsty saidpin. lt will be understood that the force of the spring 59 transmittedto the bell crank 28 through the pin 60 tends constantly to turn saidbell crank in counterclockwise direction when viewed from the top as inF ig. l and that said spring will restore the bell crank and the partsconnected to it to normal position after operation. lt will further beapparent that the spring 59, acting through the bell crank will pull therod or link 34 towards the right, this movement of pull or tension beingcommunicated from the lett-hand end of the rod to the operating lever40-43. At this point it may be noted that the detachable connectioncomprising the nut 38, 89 between the rod 34 and the lever arm 40 is ofccnsiderable convenience in that it enables me to dispense with turningmovements of the long rod 34 during adjustments, and requires only anadjustment of the nut 38, 39 by a spanner or other tool in order quicklyto connect the rod 34 with the operating lever. i

It will be seen that the left-hand line spacing mechanism provlided bymy in,- vention is simple in construction comprising few parts which maybe readily attached to a machine and connected with the line spacingpawl without requiring material alteration in the regular construction.The mechanism is edective in operation and the parts are comparativelylight. rlhe rod 34 since it is subjected to` tension stresses only andnever to compression may be made of comparatively fine wire. Theconnections between the line spacing handle and the pawl are positivelyattached and constantly connect the two parts; and a singlespring onlyis needed to restore the entire train of part-s after a line spacingmovement.

Various changes may be made without departing from my invention.
